Network computer Global

network Computer - ma aha waxaan ururka ka mid ah dhowr kombiyuutarada wada, ogolaanayo in ay is dhaafsadaan macluumaadka. network Global call markii ay dabooli dadka isticmaala oo dunida ku baahsan. Ogsoonow in shabakadaha computer ugu horeeyay ee rayid ah u muuqday oo dalka Mareykanka ah. Laakiin dadka yar ogahay in mabda 'aad u of technology ugu horreeyey waxaa la isticmaalaa in USSR ah, sidaa darteed waqti dheer ka hor nidaamka difaaca gantaalaha ugu horeysay waxaa la abuuray.

Maanta, waxaa jira kala soocidda a network si caddaalad ah u ballaaran. Sida laga soo xigtay qaybinta aan ollogga ah ee shabakadaha computer caalami ah, gobol, degmo iyo Sharaf. network computer Global shabakado ku yaalaan dhulka dalalka gobolka ama dhowr ah, tusaale ahaan, caalamka Internet. Läns dabooli aag ilaa tobanaan dhowr ah oo mitir oo laba jibbaaran, iyo gobol - waa shabakad, kaasoo ku yaala gobolka ama magaalada.

Si kastaba ha ahaatee, laba xilli muhiim ah kala soocidda ee shabakadaha - waa: WAN iyo LAN.

WideAreaNetwork (WAN) - caalami ah shabakadaha computer, oo taabanaya dhinacyo badan oo, kaas oo ka mid ah shabakadaha degaanka maxalliga ah iyo qalabka kale ee isgaadhsiinta iyo shabakadaha.

LocalAreaNetwork (LAN) - Ethernet, kaas oo ay leeyihiin kaabayaasha gaar ah ka hor inta ay sii daayo on bixiyeyaasha adeegga. The aad isku dheer «LAN» tilmaami karo iyo network xafiiska yar, iyo shabakad ballaaran dhirta daboolaya meel ka mid ah dhowr boqol oo acres.

network ugu da'da weyn caalamka waa internetka. Waxay bixisaa siyaabo kala duwan in ay ku xidhmaan kombiyuutarada fog fog, iyo isticmaalka guud ee ilaha macluumaadka iyo adeegyada loo qaybiyey.

Markii hore, shabakadaha computer caalamka ku hawlan xalinta dhibaatada helidda boosteejada fog badan iyo kombiyuutarada in kombiyuutarada oo awood badan, loo yaqaan marti-s. xidhiidhada waxay ka kooban yihiin via unswitched ama channels wareegay network telefoonka ama via ka go'an satellite shabakadaha xogta, tusaale ahaan, ka shaqeeya hab maamuuska X.25.

In ay ku xidhmaan shabakadaha sida isticmaali modem ah oo la socda a barnaamijyada isgaarsiinta gaar ah, nooca COMIT, PROCOM, BITCOM, MITEZ iyo kuwa kale. OS MS-DOS Maamulida, waxay is dhaafsadaan doonaan macluumaad la computer ah oo ay xidhiidh.

The isla dhismaha shabakad caalami ah sharaxaad ka ma aha kuwo ku adag. Shabakadda caalamiga ah wuxuu ka kooban yahay cells in ay yihiin shabakadaha maxalliga ah. In Warega läns ka kooban yihiin shabakadaha yar iyo kombiyuutarada shakhsi. Halkan waxaa ku qoran madaxda heer multi iyo awood dhismaha shabakada. Intaa waxaa dheer, qalab kasta oo ku saabsan shabakada waa in ay leedahay u gaar ah IP-address, ama aqoonsi u gaar ah.

Maalmahan, yar yar oo loo isticmaalo kombiyuutarada hal shabakadda caalamiga ah ee computer. Asal ahaan, waa - kumbiyuutarada guriga. Inteeda badan, waa kuwa macaamiishu kombiyuutarada network, kuwaas oo lagu daro maxaliga ah shabakadaha degaanka, sidaas darteed, khabiiro ugu fiirsanayo fursadaha sidii ay u bixiyaan isdhexgal wanaagsan oo dhowr shabakadaha xaafaddooda. lagama maarmaan ay tahay in haddii ay taasi si ay u bixiyaan for computer fog xiriir la kombiyuutar kasta gudahood network degaanka fog, ama qeybsanaan. doorasho ee la soo dhaafay waa mid aad u khuseeya sida tirada guriga iyo kombiyuutarada shakhsi.

Haddaba isticmaalaan xarumaha Beddelashada waxaa ka mid ah shabakadaha X.25 qalab gaar ah shirkadaha Telenet-saarka, Ericsson, Siemens sida qalabka network, Alcatel iyo sidaas, iyo sidoo kale, waayo, TCP a / shabakadaha IP isticmaali router iyo shirkadaha Cisco Decnis. Si kastaba ha ahaatee, technology ayaa weli ma taagan, iyo waxay u badan tahay in mustaqbalka waan arki doonaa urur xitaa ku ool ah ee shabakadda caalamiga ah, kuwaas oo hadda uu leeyahay saamayn weyn ku ah nolosha qof kasta.
